So I've done a little reading on quickshifters since I'm completely new to them. Pretty much all of them inform the ECU the rider wants to shift and the ECU makes the magic happen since it's already controlling the engine. The difference is method of downshifting used. Autoblippers of course have the ecu blip the throttle to make a smooth downshift. The problem with those is a failure could potentially lock your throttle wide open. The other method being used is to alter spark plug timing/ignition to advance the engine to make the downshift happen. Which looks to be more successful for the ECU to manage than throttle blip.Funny, last night I was thinking, hey someone with the service manual could probably look at the schematic
So then it is a smart switch. That's too bad as I would assume, if it's a smart switch it would be the thing telling the ECU up/down, though I guess it's possible that intelligence lies elsewhere, but anywhere but the switch seems complicated.
